LAMP STAND.

Application led. March 5, 1921. Serial No. 449,717.

To all whom it may concern:

Be it knownthat l, EMIL Hnnenok, a citizen of the United States, and a resident of New York city, county and State ot New York, have invented certain new and useful improvements in Lamp Stands, of which the following is a specification.

rIhis invention'relates to electroliersov the type ordinarily known as door or table lamps.

These lamps are usuallyconstructed lwith a wide base and a post or standard whose length varies in accordance with the -particular style of the lamp. This construction, involving the wide base and the long standard, makes the shipment and storage of these lamps a particularly diiiicult and expensive problem.

The objects oi my invention are to overcome these diliculties and to so construct the lamps that they may be readily taken apart for shipment and storage and be easily put together for use or display and to avoid the need for any special skill or care in the assembling and disassembling oit' the device. 1n the accompanying drawing l have illustrated one of the practical embodiments of the invention but wish it understood that the same may be modified without departurey from the broad spirit and scope ofthe in* vention as hereinafter defined and claimed.

Fig. 1 is a broken part sectional view of a. simple commercial form of the invention.

Fig. 2 is a plan view of the combined closure and abutment plate used at the base of the lamp stand. U

Figs. 3 and 4 are side and end views respectively of the mechanical. connecting de.

vice Yfor the sections of the postl or standard.

The lamp illustrated comprisesa suitabley base 5 from which there rises a', post orl standard 6 supportingthe lights and carrying the shade elements 7.

ln my invention the post or f standard is made in a plurality of separable sections. such as l have indicated at 8 and 9. These, sections maybev stepped one intov the end.

of the other as I have indicated at 10 and they are secured together by .means of a coupling device 11 ofthe general shape ofea turn buckle, thatis, havingside'arms providing between them a space 12 to receive an electrical connector 13 and provided atk opposite ends with screw sockets 14 and 15. A special feature of these screw sockets is that they are each open at one side thereof,

as I have indicated at 16, to accommodate Specification of Letters Patent. Patented Aug. 29, 1922.

the wires in assembling and disassembling the device.

,The connector 18 may be of any standard construction and servesV to couple together the sections of the conductorcord 17, 1S at opposite sides of lthe joint between the post sections. rlhis cord or ixture wire is housed in pipe sections 19, 20 whichhave screw threaded ends 21, 22 engaged in the screw sockets 14, 15 respectively.

f The lowermost post section is secured to the base of the lamp by a nut 23 engaged on the screw'threaded end of the lower pipe section and having a bearing against an abutment plate or disc y24 pivoted to the under side .of the base at 25. This plate closesor bridges the opening 26 provided in the base as a socket for the shouldered lower end 27 kot the post andas shown iny Fig. y2 is provided with a central opening 28 for the pipe and an arcuate slot 29, drawn from thecenter of support at 25, for the passage of the wire.

The cord emerging from the yend of the lower pipe section is usually provided with a suitable attachment plug such as l have indicated at 30 and the opening 26 provided ir` the base is made large enough to pass this p uo. f

lid assembling the device the coupling member is usually first secured non-rotatably in the end of one of the post sections. ln the case illustrated the upper end of the coupling member is tirst driven up into the socket provided therefor in the lowerend ofk the post section 8 and is held against rotation therein by reason of the outstanding sharpened websor ribs 3l whichA bite into the walls of the socket as the memberis driven into its seat. The pipe section 19 is then turned intothe screw socketk14, the

p upper end ot such pi. e section beingordinarily accessible for tiis purpose. To prevent this pipe from being screwed too far down into thev socket 14 the screw threads in the socket may extend only partv way, as I have indicated at 32. l n

When the coupling member is thus fixed in the first post sec-tion the upper section of wiring 17 may be threaded through the pipe 14 and secured at its lower end to the upper member of the separable connector. The lower section of wiring 18 is then threaded through `the lower pipe section and connectedy with the lower member of the sep-rr arable connector', the members of the connector being there coupled together enough slack being lett at opposite ends of the connector to enable this coupling together before the post sections are connected. After this the connector is pushed into its seat between the arms or' the coupling member and the post sections are telescopically engaged and the upper section turned with respect to the lower so as to screw the socket 15 down over the threaded end of the lower pipe 20.

The post may be made in as many sections as desired and after the sections are joined in the manner described the post is then mounted on the base by engaging the shouldered lower end 27 thereof` in the open socket 2G in the base, thevprotruding portion of the pipe being passed through the central opening 28 in the anchorage plate 24 and the nut 28 being applied to draw the post firmly to its seat on the base.

When the lamp is to be taken apart for shipment or the like the nut 23 is unscrewed and allowed to drop down on the cord toward the attachment plug. The post is then lifted out of its socket so as to clear the end of the pipe from the anchorage plate, after which the anchorage plate is swung on its pivot to carry the attachment plug cord through the slot 29 and hence clear of the anchorage plate. This swinging of the anchorage plate to one side also opens up the socket 26 so that as the post is lifted away from the base the nut 23 and the attachment plug at thev end of the cord can be withdrawn through the opening 26 free ot the base. The base sections are then unscrewed, the wire, during such operation being preferably lett free to turn as it will within the enclosing pipe. When the screw socket 15 becomes disengaged from the pipe to which it has been connected the post sections. may be separated `tar enough to give access to the connector which is then lifted out o'l its seat in the coupling member and is separated. lVhen this is done the lower member of the connector may be turned so as to carry the Acord 18 attached thereto laterally through the slot 16 in the sideof the lower screw socket. This then enables the complete sepration of the upper post section, with the attached coupling member, Yfrom the lower .post section. The slot 16 in the side oi the upper screw socket. enables the connector to be completely withdrawn sidewise from its seat in the coupling member and is of particular advantage where the connector occupies practically the entire length of the space between the arms. y

rlhe invention, it will be seen, provides a simple, practical and at the same time inexpensive means of ydetachably `connecting the structural parts of a lamp stand, which will hold the parts lirmly together and which at the same time will enable quick and easy assemblage and disassemblage.
